EBERHARD SCHNEIDER, OF NEW YORK, N.Y.

ADJUSTABLE FILM-PERFORATING MACHINE.

Application filed March 14, 1911.

To all whom it may concern:

Be it known that I, EBERHARD SCHNEIDER, a citizen of the United States,and a resident of the borough of Manhattan, in the county of New Yorkand State of New York, have invented certain new and useful Improvementsin Adjustable Film-Perforating Machines, of which the following is aspecifica tion.

This invention relates to an adjustable film perforating machine, whichis an improvement of my film-perforating machine described and claimedin my United States Patent No. 788,851 bearing vdate May 2d, 1905. Itsprincipal object is the production of a machine with which perforationsthat are of different pitches, or different distances apart can be"formed in films and particularly picture films. This variation of thepitch can be accomplished while the machine is in operation, and whilethe punches are perforating the film. The different pitches of theperforations are obtained by locating a film on the drivin sprocket drumof the machine so that di erent teeth of the said drum become effectivein propelling said film, for the different pitches while the films arebeing perforated. The teeth of the sprocket drum extending from thecircumferential surfacethereof being located at different verticaldistances from the axial center of said drum for the various pitches,the horizontalmovement of the film, that is its velocity 'is therebyvaried, causing the perforations made by the punches of the machine tovary at the will of the operator.

In the accompanying drawings Figure 1 represents a side view of a filmperforating machine exemplifying the invention, Fig. 2 is a partial topplan view of Fig. 1, Fig. 3 is a right hand end view of Fig. 1, Fig. 4is a partial section of Fig. 3 on the line 4, .4, Fig. 5 is a partialenlarged section of Fig. 1 on the line 5, 5, Fig. 6 is a section of Fig.5 on the line 6, 6, Fig. 7 shows a partial enlarged section of Fig. l onthe line 7, 7, Figs. 8, 9 and 10 show partial end views of the filmadjusting mechanism of the invention, Fig. 11' showsa side view of afurther modification of the drum adjusting mechanism, Fig. 12 is a topview partially in section of an adjustable sprocket drum, and Fig. 13 isa bottom plan view of Fig. 12.

The machine is represented with the bed plate 20 from which extends theframe 21 Specification of Letters Patent.

with the bracket 22 having bolted thereto the guide sleeves 23. Singlejournal hubs 24, 25 and the double journal hub 26 are formed with theframe 21. In the hub 2a is journaled a driving shaft 28, which at oneend carries the fly wheet'29 having a circumferential groove for thebelt 30. A bracket 35 extends from the bed plate 20 which has extendingtherefrom the journal pin 36, on which latter is journaled a doublepulley 37 with the grooved disks 39 and 40. The belt 30 connects the flywheel 29 with the grooved disk 39. A motor 44 is supported on the bedplate 20, and on the shaft 45 of the said motor is fastened a groovedpulley 46. A belt 47 connects the latter pulley with the grooved disk40. The shaft 28 has fastened thereto the gear 50 that has extendingtherefrom the crank pin 52. A cross head engages the crank pin 52 andhas extending therefrom the plungers 56, that carry the punches 57. Thesaid plungers are guided in the guide sleeves 23 of the bracket 22. Aspindle is journaled in the hub 26 and carries at one end the gear 61that carries the pin 62 and meshes with the gear 50. At the other end ofthe spindle 60 is fastened the pulley 63. A spindle 66 is journaled inthe hub 26 and carries at one end the star wheel 67 which latter isoperated by the pin 62.

The other end of the spindle 66 carries the pinion 68 which meshes withthe gear 70, that is journaled on the sprocket drum shaft 71. The gear70 has a pair of slots 72 through which extend the screw pins 73 thatare in threaded engagement with the'adjusting support 74 fastened to theshaft 71. The other end of the shaft 71 carries the driving sprocketdrum 75.

A pin 80 extends from the frame 21 and carries the adjustable bracket 82in which are pivoted the guide rollers 83. The said rollers can bear onthe film 84 to be described and that is engaged by the pins of thesprocket drum 7 5. In the bracket 82 is formed a slot 85 which engages atightening screw 86 that extends from the frame 21, and by means ofwhich the bracket 82 can be locked in different operative positions.From the lower end of the bracket 82 extends the arm 87 in which isjournaled the guide roller 88. The film 84 in the present case is adeveloped negative which has formed near its edges the index marks 89,and in the present instance three such marks swinging end the tensionroller 157. spring 158 maintains the said roller 157 in are formed onopposite sides of each picture, the central mark of each three beingopposite the center of its accompanying picture.

From the upper end of the frame 21 extends the arm that supports the pin91 on which is journaled the take off reel 92. An arm 96 extends fromthe frame 21 and carries a spindle 97 on one end of which is fastenedthe take up reel 98, and on the other end thereof is secured a pulley99. A belt 100 connects the pulley 99 with the pulley 63 on the spindle60. A support extends from the bed plate 20 and a bracket 106 extendsfrom the frame 21. A cover plate 107 has openings 108 with the glasscovers 109 and the'openings 114 for punches 57. The cover plate '107 hasa longitudinal depression 113 to avoid frictional engagement with thefilm 84. A discharge funnel 115 in the support 105 extends under theopenings 114. 'An end plate 116 extends from the support 105 and has anopening for the socket 118 of the electric lamp 119, which latterextends below the glass covers 109. On the upper face of the cover plate107 are adjustably secured guides 120, by means of the screws 121. Slots122 in the said guides enable the adjustment thereof on the plate 107. Abracket 125 with the arms 126, 127 is adjustably mount-- ed on theguides by means of the screws 128. A screw 129 with a lock nut iscarried on the bracket 125. One-end of the bracket has hinged thereto apressing plate 130 by'means-of the pin 131,-which extends through thelugs 136 of the pressing plate 130. Openings 137 in the said-plate 130allow the punches -57 to pass therethrough and register withthe opening114. A vertical pin 140is-secured in the pressing plate'130 and passesthrough a slot '141 in the bracket 125. A spring 142 encircles'the pin140 and bears between said bracket 125 and the said pressingplate.

A guide roller 145 extends from the frame 21 adjacent to'the cover plate107 in the path of the film '84. A frame 148 is hinged to the frame 21by means of the screw pin 149. A prism 150 is supported in 'the saidframe .148 to receive the light rays from the lamp 119 and that passthrough the glass covers 109 and the film 84.

A bracket .155 is hingedto the frame 21 on the screw pin 156 andsupports on its A engagement with the film 84, and a pin 160prevents thebracket 155 lowering too great a distance. On a screw pin 162 is pivotedthe-adjusting lever 163, which carries an adjusting roller locatedbetween the punches 57 and the sprocket wheel 75. On the swinging end ofthe lever 163 is carried a threaded block 164 having a pointer 166. Athreaded spindle with the standard knurled head 171 is carried in asupport 172 extending from the frame 21 and its lower end is in threadedengagement with the block 164. A bracket 173 with the scale 174 extendsfrom the frame 21 and is located in the path of the pointer 166.

On the cover plate 107 are secured brackets 178 on which are fastenedplates 179 with the pointers 180 that extend over the paths of the indexmarks 89 of the film.

Adjacent to the support- 105 is located a support 181 which carries thelens 182. A screen 183 is located in the axial line of said lens toexhibit the film 84 with its index marks 89.

Referring to Fig. 8 the di'iving sprocket drum 75 engages the film 84 bymeans of its pins when they reach the location designated by 185, and atwhich position the distance through which the film is propelled can berepresented by the line 186 giving the minimum speed of propulsion tothe film 84, by virtue of which the perforations are nearer to eachother than what I term standard pitch.

In Fig. 9 the film 84 is engaged by the drum whenthe pins reach theosition 187, and with this engagement the e ective speed of propulsionof said film can be designated by the line 188, by virtue of which thefilmwill be perforated with holes that are separated from each other bywhatI term the pitch. '7

3 In-FigilO the film 84.-is engaged or driven when? the pins of-thesprocket drum reach the positions-indicated at190, andtheeffective=speed-of propulsion of said film can then be designated bytheline 191,"by virtue of whichthe film will beperforated :with holes;that 'are"=separated '+from each other by a-distance greater than thesaid standard 'pitch. I Fig. llzrepresents'means for horizontally movingthe sprocket drum shaft 71, and comprises a pair of frames 200, one ofwhich'only is shown in the drawing, and in each of which is located acrosshead201 for *the shaft 71. A screw 202 has one end connected tosaid crosshead 'and is in threaded engagement'with said frame. Arlocknut 203locks the screw inioperative position.

The adjustable sprocket'drum shown in "Figs. 12 and 13 is representedwith the shaft 210 to which is keyed-a support-211, that has formed inits circumferential surface guide pockets 212. .The shaft 210 isthreaded at 213 'and 214 for thetapered end supports 220 which have;formed therewith the threaded ends 221, and the cavities 222 ment withthe ends 221 and have the beveled surfaces 232that are in engagementwith the tapered end faces 228. Touse the drum to locate the film inengagement with different pins thereof the operator first disengages theclamping nuts 230 from the sprocket bars 225, and then the end supportsare turned to either approach or recede from each other, and finally theclamping nuts are again located to clamp the sprocket bars 225 inoperative positions.

To perforate a finished developed film which preferably has index markswith each picture thereon, the said film is mounted on the machine asshown in Fig. 1, extending from the take-off reel 92 to and under thetension roller 157. From thence it extends over the cover plate 107 toand over the sprocket drum 7 5 extending under the pressing plate 130.From the drum the film extends under the guide roller 88 and finallyleads to the take-up reel 98. For the efficient operation of the machinethe horizontal distance between the center of the sprocket drum 75 andthe line joining the pointers 180 is fixed, so that a film will bepunched with perforations of standard gage when the roller 165 slightlydepresses the same and the film is propelled when the teeth engage thesame as shown at 187 in Fig. 9. The operator thus engages the film withone pair of opposite holes in the same preferably in the positionindicated at 187. Then the film is observed through the prism 150 or theprojection thereof on the screen 183 and the location of the index marksis noted with reference to the pointers 180.,

If the index marks are a little to the right of the pointers 180 as seenin Fig. 5 it shows that the pictures have been photographed on the filmat too great a distance apart and the machine must be set for a longerpitch of perforations which is accomplished by turning the head 171 tolower the roller 165 until the index marks of the picture of the filmcoincide with the pointerslSO. The film will then be propelled by thesprocket drum with the engagement thereof of the pins indicated at 190shown in Fig. 10. If in the first instance after a few perforations havebeen made in the film any of the index marks appear to the left of thepointers 180, it indicates that the pictures have been photographed onthe film too close to each other and the film must be perforated for ashort pitch which is accomplished by turning the head 171 to raise theroller 165 until the film is engaged by the pins when in the positionsindicated at 185 in Fig. 8.

The machine provides a means of perforating a film so that itsperforations will be synchronized with the difierent distances thepictures are apart, obtaining a machine by which pictures differentdistances apart can be projected from a picture machine with the sameresults on a screen as with a film on which the pictures are all thesame distance apart.

It will be noted that the variations of pitches of the holes punched inthe film is produced by the different locations of the adjusting roller165, which causes the pins of the sprocket drum to become effective atdifferent angular positions thereof. The engagement of the film with thesprocket drum at these different angular positions thereof can also beaccomplished by setting the drum 75 in different angular positions bymeans of the screw pins 73. A similar result may be obtai n e d byhorizontally moving the axial line of the drum, by locating thecross-head 201 in different positions with the screw 202 (Fig. 11.)

When the machine is used for perforating a regular sensitive positive ornegative stock, it is engaged with the sprocket drum 75 as shown inFigs. 8, 9 and 10 depending respectively Whether perforations of shortstandard or long pitch are required.

It is to be noted that 'a perforating ma chine could beconstructedwith amoving fork to engage the film. so as to vary the speed of travel Whilebeing operated upon by the punches. It 'will alsobe noted th'at when thedrum is used, if there is a slight creeping of the film thereon, .itdOBSrIIOt vitiate the operation of the invention.
